INTRODUCTION Smart cities are becoming not only a reality but also more popular and spreading day by day. In fact, the deployment of smart and cognitive cities is expected to be very dominant in several regions of the world in the near future due to their advantages and merits in making our life easier, faster, simpler, and safer [1]–[4].

However, still thousands of people die in car accidents/collisions every year. For example, over 1.2 million died, for example, in traffic accidents around the world in 2016 [1]. There are a number of different reasons for road accidents/collisions in different countries. Nevertheless, the major cause of these road collisions is mainly driving the car under unpredicted weather conditions. Iqbal et al. [1] note that 50% of the fatal collisions happens while driving under a speed of 55 km/h. We therefore need a system where the speed limits are set according to the existing weather, traffic, and road conditions. Smart cities are composed of a massive amount of smart, intelligent devices that have sensing, computing, actuating, and communication capabilities. These devices are designed in such a way that reduces human intervention through cognition and automation in communication. They are commonly termed as internet of things (IoT) devices, which are expected to dominate the infrastructure of smart cities. Among the massive design requirements of IoT devices, low complexity with highly reliable communication channels comes as a key priority besides energy efficiency, latency, and security in emerging 5th generation (5G) services [5].

Of course, the impact of such an enabling technology is expected to be revolutionary. The new infrastructure for communication is expected to transform the world of connected sensors and reshape several Journal homepage: http://telkomnika.uad.ac.id

existing industries. Such a revolution would, of course, require extensive research and development for the coexistence and device interoperability with 5G systems, and deployed sensor networks. This is a must for cooperative and smart sensing techniques, improved quality of service (QoS), and energy-efficient architectures in new intelligent transportation systems (ITS) infrastructure. This can be achieved by developing new sensor/5G protocols and standards, which can communicate with the cloud reliably.

Focusing on optimization of the ways, the data is exchanged between the sensory devices and applications in IoT, and cyber-physical systems have led to the 5G/IoT integration as well. For example, studies on approaches tol constructl higher level abstractions of data at local gateways are proposed to reduce the traffic load imposed on the communication networks that provide the real-world data [5]. Test beds and real-world data sets are popularly employed to analyze the methods proposed.

With this recent revolution in wireless telecommunications, several advanced solutions relying on wireless communication standers have been proposed to provide ITS in the IoT paradigm. For instance, Ali et al. [2] projected an automatic speed control (ASC) system that adjusts the speed of the vehicle according to the speed limit on the road. The feasibility of a smart box called “telematics,” which has the ability to capture, analyze, and communicate, is being studied in cooperation with IBM’s engineering and technology services. Using multiple microprocessors and tiny sensors attached to the vehicle body, it is able to observe the vehicle’s velocity, for example, and compare it to the upper speed limit of the road. In case the speed of the car is higher than the announced limit allowed by authorities, the box will verbally notify the driver. Moreover, a digital image processing system has been proposed by Baro et al. [3] while utilizing on board cameras to read and recognize signs at the side of the road and send the warning signal to the driver and/or directly control the car. Different versions of this system have been investigated intensively all over the world.

The results in Beek et al. [4] have shown that this solution is able to cut down the accident rate by 35%. In the near future, the speed control system will be very dependent on the standard of IEEE 802.16 to locate each vehicle and satisfy the demands of the required real-time services such as voice and video [5].

In IEEE 802.16, there are different medium access control (MAC) scheduling services, such as unsolicited grant service (UGS), real-time polling service (rtPS), and non-real-time polling service (nrtPS) to provide better QoS. There are two commonly used schedulers for real-time traffic: the UGS and the rtPS [6].

However, these schedulers do not fulfill the requirements for the real-time services in smart cities. Hence, the suitability of al batch Markovian arrival process (BMAP) is analyzed [7] for modeling of IP-based data traffic.

Accordingly, the BMAP has been found to be better in comparison with Markovian-based models. Hence, we propose a real-time-BMAP (RT-BMAP) model for real-time services. The objective of this approach is to provide the required QoS level with the minimum delay. Accordingly, the majorl contributions of this paper are as: − We present the enhanced-rtPS (E-rtPS) integrated with RT-BMAP to solve the interference probleml inl the smart cities paradigml optimistically. − Our proposed approach has less computational overhead and betterl performance in terms of resource utilization. − The examination of real-time results shows thatl the proposed framework outperforms the existing IEEE 802.16 services in terms of delay, throughput, and reception percentages.

For more readability, a list of used abbreviations along with their definitions is provided in Table 1.

The rest of this paper is organized as: section 2 overviews related works in the literature. Section 3 presents a detailed description of the proposed framework. Section 4 discusses extensive simulation results. Finally, Section 5 concludes the work in this paper.

RELATED WORK By 2021, the mobile networks will triple the amount of used smart devices in 2016. In addition, mobile video services will increase nine times what we experienced in 2017. Given that ourl resources are limited and QoS is critical, the system basestation (BS) shall allocate the existing system bandwidth proactively. In smart cities, smart transportation systems, cellular network, wireless sensor network (WSN), device-to-device (D2D), and many of these smart paradigms involve the wireless mobile multimedia communications and/or transmissions. Specifically, the D2D has received increased attention from wireless cellular networks because it can noticeably off-load the network traffic and reduce the transmission energy since the communicating devices are in close proximity to each other [2]. This close proximity makes it anl eminent networking architecture for relay-based transmissionl employed by energy-constrained devices, suchl as smartphones, tablets, andl personall digital assistants (PDAs). Therefore, it is considered to be vital to improve the energy efficiency of D2D networks while maintaining their reliability in terms of the experienced throughput and latency. Most of the existing works have consideredl the direct link situationl for the degradation of long-distance communicationl [2], poor propagation [3], and interference [4]. As relay-based transmission can improve the longer distance D2D communication, most of the researchers have given their attention for the multi- hop D2D communication.

Abdulkadir and Al-Turjman [5] deal with spatial density and power transmission to get better transmission capacity. However, it is declared without specifying a routing technique. Al-Turjman et al. [8] propose a multi-hop routing technique to maximize the hop count of the networking systems. But then, it is proven undependable to minimize the distance between the users. Since the existingl relay-based techniques do not consider the energy efficiency for the D2D communication, there is a need to formulate a combinatorial optimization that improves the energy efficiency of such communication systems. Accordingly, technological advancements are balancing the act between bandwidth usage and time delay in any data delivery approach. In addition, low complexity with high-reliability communication comes as a first key priority besides energy efficiency, latency, and security [5].

There are two main categories of approaches that are focusing on addressing these challenges; the distributed versus centralized approaches. The distributed approach is a distributed routing in the network, which is very popular, and it has many sub-approaches. Distributed coding is also proposed and adopted to be used in future 5G and beyond systems as an indispensable channel coding scheme [9], [10].

However, different channel codes are constructed and generated according to a pre-specified value of the signal-to-noise ratio (SNR). This issue becomes even more complicatedl with fading channel consideration due to multipath existence. In an attempt toward proposing reliable channel codes which considers fading conditions, several studies have been conducted and performed in the literature. In [11], a multilevel fading channels, which utilizes the nested coding, has been exhibited. It was demonstrated that this approach tends to tackle fading channels with a limited number of states. In [12], polar codes are connected to remote channels.

A strategy for acquiring the Bhattacharyya parameters related to Rayleigh channels is exhibited.

In [13], lower and upper limits on Bhattacharyya parameters were selected to develop competitive channel codes.

Boutros and Biglieri [14] detailed the coding procedures for the radio frequency (RF) channel with realized channel state data at the two ends of the connection with known channel dissemination data. Another example on TELKOMNIKA Telecommun Comput El Control, Vol. 21, No. 2, April 2023: 280-289

investigating the coding for block-fading channels can be found in [15]. The channel use is exhibited with the objective that codes could be grasped to be encoded over isolated squares in [16]. In [17], the creators analyze the general sort of the superfluous information trade and coding with multistage understanding. In light of this examination, they proposed a graphical structure methodology to create channel codes for picture hindrance.

In Al-Turjman et al. [18], a clear system for the improvement of portable channel codes considering Rayleigh impacts was displayed. The sub-channels are shown as multipath obscuring channels, and their varying decent requests are pursued. In [19], codes are planned solely for square-based channels. The authors-built channel codes customized forl square fading channels while polarizing them with codes. The accomplished arrangements are shown to convey a significant increase contrasted with ordinary coding. Mehmood et al. [20] gave an elective structure of this methodology by treating the shadowing, fading, and coding of the channel as a solitary element.

This empowers developing channel codes by mapping the codes with shadowing and fading effects. The acquired codes are adjusted to divert vacillation in versatile situations. Arikan [21] proposed a scheduling scheme of dynamic carrier aggregation (DCA) to provide higher energy efficiency in uplink communication. In Santos [12] have not considered the uplink real-time scheduling and resource allocation framework for the demand of the 3rd generation partnershipl project (3GPP) long term evolution-advanced (LTE-A) networks.

Xu et al. [22], an orthogonal frequency divisionl multiplexing (OFDM) approach under multipath fading channels is proposed. In this methodology, the codes are permuted with the goal that the code bits contrasting with the hardened bits are doled out to subcarriers causing ceaseless piece goofs. This change can be considered as a kind of interleaving that can distinguishably upgrade the channel coding. Nevertheless, changing the codes depending onl the channel is not always required. That is onl the grounds that it would result in a persistent change inl the code of the correspondence channel type. This is viewed as a bulky, complex, and wasteful, particularly for cloud-based applications. As al conclusion, the greater part of the previously mentioned methodologies accepts either the LTE-A or the IEEE 802.16 in theirl correspondence conventions. However, these measures have not been viewed as productive in planning. Subsequently, it is yet an open research issue [23].

Inl this work, we aim at proposing an adaptive framework for dynamic channel management in smart cities. We propose a novel design for the mobile vehicular cloud infrastructure that takes into account varying weather, road, and traffic conditions. This framework utilizes the latest channel codingl techniques while utilizing the existingl cellular infrastructure to stream data, sound, and video with the least latency.

FRAMEWORK DESCRIPTION In this section, we recommend a complete depiction for the proposed vehicular cloud frame- work.

We define our framework components as: − Management and control center (MCC): this componentl controls the velocity of the vehicle depending on the street, traffic, andl surrounding environment conditions. − Speed limit transmitter (SLT-x): this component is used to communicate the speed limitl to the end-driver. The speed limits are transmitted as a wireless message. The MCC controls/adapts the speed of the vehicle based on road, traffic, andl weather conditions, given thatl enough road-side units (RSUs) are located at predefined points on the road. − Speed limit receiver (SLR-x): this component takes the transmitted street upper limit and displays it clearly in the vehicle. It will also be communicated tol the driver’s smartphone. − Vehicle speed sensor: this component is required to measure the speed of the vehicle accurately. The speed measurement system that already exists in the car can be used as well. − In-vehicle microcontroller: its main taskl is to compare the actual speed to the road speed limit, which is received by the SLR-x. Based on the vehicle speed, the controller may generate an audio warning or may communicate such incidence to the MCC through the 5G network via the driver’s smartphone. − 5G modem: this modem is used to send a speed data to a central station, which is monitored and operated by any other governmental or private entity. − Drivers’ records server (DRS): it stores information about the drive. The DRS is updated when the global system for mobile communications (GSM) modem sends a signal from the driver’s car. The DRS can be accessible by third parties with the approval of the driver. Such third parties include parents, family members, and insurance companies.

3.1. Functioning of the vehicular cloud framework Figure 1 shows a simplified schematic for the planned vehicular cloud system in normal conditions.

The SLT-xs are connected to the MCC component through the public switched telephone network (PSTN) and the GSM/5G networks, which are usually connected to cloud data centers. They are controlled by the MCC, which recommends changing the speed limit depending on the road, weather, and traffic conditions [24].

The MCC gets the required information from the patrol police, forecast stations, and driver’s smartphones.

The vehicle speed is continuously compared to the received speed limit, which is also displayed to the driver.

Hence, the driver will always know the upper limit of the street he or she is on. This is a better method than the conven- tonal speed limit signs located on the side of the road. Ifl a driver is driving below the speed limit, there is nothing to do except that it might be a congestion case. Ifl the vehicle speed limit exceeds the received one, al warning signal will be generated to alert the driver that he or she exceeded the speed limit. Ifl the driver does not respond within al given period, the In-vehicle Microcontroller sends al note (violation) through the 5Gl modem to the DRS. The violation can also be sent to the driver’s smartphone. The violation can also be recorded using various network-positioning techniques. Other forms of violations such as tail tracking and red light tracking can be motored in the car, which has other types of sensors. Inl such a case where a violation was recorded, the DRS canl inform the driverl instantaneously through his or herl mobile/e-mail/ mail, or by some other IEEE 802.16 standard means. We remark that this study focused onl the voice over IP (VoIP) service as an example of the exchanged realtime contents overl the vehicular cloud.

3.2. Registration phase We assume that RSUs are located in different places along a given road. Local controllers (LCs) are static BSs in the city. mobile controllers (MCs) are sensing platforms attached to vehicles.

We use a minimum spanning tree (MST) algorithm to select an LC at each route. Each MC is considered as a node in the MST, whereas all RSUs are considered as terminal nodes, as depicted in Figure 2. Accordingly, this registration phase is summarized in the following four main steps: − Step 1: the MC first transmits a control message such as a Hello message to all RSUs in range to determine the layout of the network as depicted in Figure 1. − Step 2: the RSU computes its associated delay and compares it with the neighboring RSUs in the same depth based on the IEEE 802.16 standard means. The RSU with the lowest delay declares itself as the LC. − Step 3: the selected LC broadcasts a message to the MC and all RSUs in range, with the updated information about all the nodes; these are vehicles and RSUs. All nodes contacted record the routes to an MC in their flow table. − Step 4: the previous three steps are repeated, and finally, the MC institutes a global layout and sends it to all LCs, RSUs, and vehicle networks.

We remark that RSUs can calculate the number of Hello messages sent previously as the vehicle moves and updates each other and the nearby RSUs. This helps in improving the stability of the vehicular cloud system by averting sparse network conditions, thus selecting an LC with the highest connectivity. We similarly calculate the hop count by looking at the number of RSUs a message has passed by (see Figure 2). At the end of this phase, the selected LCs create a localized global view at each depth from the MC. Therefore, different kind’s of controllers are used to reduce the system burden from the single main controller and reduce the overall overhead and delay.

Figure 2. A schematic for the vehicularl cloud in smart cities 3.3. Channel coding phase We assume an IP real-time subsystem-network (IRS-N)-based framework utilizing the channel quality indicator channel (CQICH) for demanding the bandwidth from the free wireless channel resources. We make use of the two reserved bits in the universal MAC header of IEEE 802.16. One of these bits, which is called the grant size (GS) bit, is responsible for informing the BS about the state of the voice transition. For example, when the voice connection of the MCC is on, the MCC ascribes the GS bit to zero. Moreover, the MCC imparts any changes in the voice transition using the traditional MAC header. So, the BS keeps informed of the changes happen to the voice state with- out causing any MAC overhead. Alternately, the uplink resources can be used to get the bandwidth request process while using the MCC and BS resources to monitor the GS bit transmission.

The BS assignment considers the uplink resource to realize an enhanced RT-BMAP. Accordingly, many performance problems, such as delay, medium access, bit/frame error rate, and resource management, arise while supporting the multimedia services in a smart city. We assume the reserved bits of IEEE 802.16 are used for this purpose. Furthermore, the MCC is used to privilege the SC bit. The IRS-N employs the required bandwidth in order to hold the uplink usage and the frame of voice codec acquired by the network.

RESULTS AND DISCUSSIONS In this section, we present the results of our planned framework. It involves hardware and software implementation parts. The main purpose of the hardware part is to construct a simple test bed for such projects/ideas. This test bed has been proved to be very helpful with the cost approximation, and itl provides critical information about design challenges such as the delay and systeml throughput. This simple test bed is composed of three subsystems: the in-vehicle subsystem connected via cellular networks, the IP-based network (internet), and the MCC represented by the network client. E-rtPS as an online resource for voice services.

Also, we deploy real-time client (RC) and real-time server (RS) as agents to support the voice call creation and dissolution. These agents use the real-time transport protocol (RTP)/user datagram protocol (UDP) to control messages transmissions.

We assume the IEEE 802.16 model is built in the MAC layer to use UGS and we remark here that we assumed ten cars while obtaining the results in this section for realistic verification purposes. The MCC is implemented via Ubuntu PC (laptop) for experimental purposes. The car toys were equipped with Arduino boards attached to the general packet radio service (GPRS) modules. To evaluate the performance of the assumed resource allocation framework in the central cell, we consider using 5 MHz LTE-A with 19 cells working at 2.0 GHz as a wireless cellular network. For each user, the packet arrival process follows the Poisson distribution with a mean arrival rate of 1 kbps. In Table 2, our stimulation parameters are presented. Figure 3 depicts the use of an IRS core function in Ubuntu, consisting of proxy call session control function (P-CSCF), interrogating call session control function (I-CSCF), servicing call session control function (S-CSCF), and home subscriber station (HSS) in order to monitor the quality of the online service. The system depicted in Figure 3 does not only possess the ability to allocate the network service resources but canl also mask out roaming restrictions [25], [26]. We use IRS core functions to transform voice connection to real-time service. The data can be transformed inl serial or parallel mode to investigate the efficiency of E-rtPS with RT-BMAP compared to UGS and rtPS in [15].

Figure 4. Throughput versus number of calls

In the work [27]-[32] say that through the knowledge of 3GPP, RTS provides a better service scalability to the devices connected; therefore, an IRS core system with features of LTE-Advanced has been deployed to provide better scalability and services. In this study, the core network is assimilated with HSS to analyze the stability of voice services across available networks. Moreover, the IRS core is embedded with its CSCF to generate a realistic test bed. Since the system is designed for real-time services, we gradually increase the voice connectivity in order to examine the system throughput and connectivity delay. Moreover, an emergency call is registered as an unidentified caller to analyze the session setup delay and throughput of real-time services. We perform an experiment to weigh the performance of the session initiation protocol (SIP)-based VoIP compared to IRS core using wireless connectivity and also to inspect the voice connectivity delay and throughput of the network. We employ the use of IRS clients and packet analyzers in order to establish a connection between VoIP call and service connection. As depicted in Figure 4, the throughput of the proposed algorithm is much higher compared to UGS or rtPS. Moreover, Figure 5 shows that the delay of the proposed algorithm is lower at all critical points in comparison with the other services. It is imperative to note that getting the predefined delay of a service is important in the system of IEEE 802.16d/e [5] for the packet with delay violations.

Figure 6 depicts the bit error rate performance versus the energy per bit of the wireless channel codes using our proposed framework. From this figure, we can conclude that the achieved performance over a multiway channel is almost the same as that obtained in [16]. The gain is also attained as a result of canceling the dispersion and fading effects. This can dramatically enhance the mobile communication channel performance in terms of reliability. Meanwhile, Figure 7 depicts the frame error rate performance versus the energy per bit of the wireless channel codes at varying block sizes. Obviously, as the block length increases, the performance gets improved. It is worth mentioning that the obtained reliability in terms of bit and/or frame error rate of the proposed framework makes the designed codes more appropriate over multipath fading channels. However, this might be associated with a slight channel loss at the maximum exchange rate.

Therefore, quantifying the amount of data exchange rate incurred by the proposed frameworkl is recommended.

The proposed approach integrates RT-BMAP tol analyze the throughput rate and average packet delay.

It enables using the same coding design used for multipath selective channels while maintaining the same reliability performance in terms of delay and throughput. In future work, data that is collected from the RSUs will be published in the cloud after a preprocessing stage. The cloud will be able to employ machine learning and prediction techniques towards more efficient decisions. These decisions will be communicated back to relevant drivers on the road.
